BRAKE-BEAM STRUT AND FULCRUM.

Be itknown that l, Enwa'nn ll. BAUER, a citizen of the United States, residing at llammond, in the county of Lake and State of Indiana, have invented certain new and useful Improvements in Brake-Beam Struts and Fulerums, of which the following is a speeillcation.

My invention concerns improvements in the struts for trussed brake beams and in the fulcrums for the operating levers. Its aim and object is to provide a simple strut and fulcrum which can be. readily assembled, which will possess great strengtl1,a11d which will be economical of manufacture.

In the preferred embodiment of the in vent-ion the strut is made of two bars riveted together near their inner ends, the ends proper of the bars belng bent to extend n1 opposite directions and lying against and riveted to the web of the compression member of the beam. A suitable saddle or seat for the tension rod is secured to the pair of bars near their other ends and the lever may be fulcrumed to the bars or straps either outside of the tension rod or between the same and the compression member. In the specific form shown in thedrawings the seat or saddle has laterally-extended portions located in apertures in the two bars of the strut and bearing against the metal at the edges of the apertures, the tension rod, as is obvious, passing through the apertures and bearing on the seat or saddle.

On the accompanying drawing I have shown the most desirable embodiment of my invention, and on the (ll'll-IllflpYlllUll lorms a part of this specification.,-.l-igure 1 is a section through a brake beu-ui showing ihe strut and fulcrum in elevation, the channel compression bar being sectioned on line While the tension bar is cut centrally of the strut; Fig. 2 is a plan view of the cclllrnl )ortion of the brake beam embodying the invention shown in Fig. 1: and Fig. 3 u perspective vice" of the tension rod seat or saddle.

As is usual, the brake bea in has a cmnpression bar 10, which. may be ol channel crosssection if desired, and a tension rod ll fastened at its ends to the ends of the compres sion bar in any of the approved well known methods. Between llntwo, at the center of the brake beam. is a combined strut and lidcrum 'composed in the present instance of Specification of Letters Patent.

Application filed November 11, 1907. Serial No. 101,686.

two bars or metal straps l2 and 123, parallel for the greater portion of their length-and oil'set toward each other at their inner ends and riveted. iogether at this point by a rivet 14. The extreme inner ends 15 and 1(3 of the bars 12 and It} are bent ointwardly in. opposite directions and lie against the face 0' the web of channel bar ll), brine; secured thereto by the rivets l7. Near its outer end each of the nth ol bars 12 and IE3 is provided with a slightly elongated aperture le extended there-through, the two apertures aecol'nmodating not only the tension. rod 11 but also the laterally-extended cars l.) of a tension rod seat or saddle 530, the main. body 2] of which is located between. the bars 12'a1nL13 and fastened thereto by a transverse rivet or bolt 22. The front face of this seat or saddle, and of the cars 19 which form prolongations thereof, is curved at .23 to corre spond to the cum-*ature and camber of the tension rod 11. Arising from the top face of this seat or saddle is a pair of apertured ears 24 to which a brake hanger may be attached. The operating lever 25 may be fulcrumed on a rivet or bolt 26 passing through holes 27 at the extreme outer ends of the bars 12 and 13, or, if desired, the lever may be located between the tension and compression members of the beam, in which case the rivet or bolt 21; upon which. the lever turns would be passed through the apertures 28 of the bars 12 and 13.

To those skilled in the art it will be apparent that my improved strut and l'ulcrum possesses extreme simplicitv,.that it is easily and economiwtlly manul'm-tured, and that in case of dama it can be readily repaired. ()n'in; to the 'l'act that the ears or projections 1.l ol' the seat or saddle are l mited .in the apcrlures lb and bear against the rear walls 29 ol' the apertures, 1ll'iL('ll(2l-ll all ol the strain imposed on the strut b the tension rod transmitted directly in the bars 12 and 13 and is not placed upon the rivet 22 holdinp the. seat or saddle in place.

It is to be \llldvlslnml that various minor mcclnulicul llHlll s may be made in the structure shown and descri oul dcpurlure from the substance ol'- my in \vntinn as set l'orlh. in be appended claims.

1 claim:

1. In a brake beam. th cmnbination of a compression bar, a tension member, a strut between said cinnpression bar and saidteni d herein within o 'iposite directions, said bent ends lying against and fastened to said eompressionbar,

and. a saddle or seat on whieh said tension member bears associated with said bars, substantially as described.

2. :In a brake beam, 'the combination of a compression bar, a tension member, a strut between said eompression bar and said tension member and having portions spaced. apart, said spaeed-apart portions having apertures therethrough, and a seat or saddle on which said tension: member bears having parts located in the apertures of said strut and bearing against the walls thereof, said tension member passing through saidv apertures, substantially as described.

3. In a brake beam, the combination oi" a eonrpression bar, a tension. member, a strut between said compression. bar and said tension member and having apertnredportions spaeed apart, and a seat or saddle on whieh said tension member bears located between and riveted to the spaced-apart portions of said strut and having projections located in the apertures ol" saidv strut and bearing against'their walls, said tension member pass ing through said apertures, substantially as described.

4. In a brake beam, theeombii'iation. of a compression bar, a tension member,a strut between said compression bar and said ten sion member and. having'apertured portions spaced apart, and a saddle or seat on. which said tension member bears loeated between and riveted to said spaced-apart portionsof said strut and having projections located in said. apertures and bearing against their walls, said seat or saddle also having means i' or attaehm ent of a brake beam hanger there to, substantially described.
